Status: offline 		May 2008 issue #54 . Is anyone planning on building this little plane? Several in my club are planning to start at least 6 next monday. If you have built this plane please post your results and any mods you may have made. This is going to be most of us first build like this and need some advice.

Status: offline 		You might want to post which design it is and the month of the magazine. Fly RC has full size plans on a regular basis and no one will know which you are reffering to in a few weeks. I seldom see the magazine so I don't know either.

Status: offline 		Good idea Bruce I edited my first post to add the Issue info . A club member who has been doing this for along time and who is going to be guiding us in the ways of the plane building force, came up with a bill of materials. Looks like it going to come togeather

Status: offline 		I'm planning on building my own "Scratch". I just got the plans enlarged today, and I'm going to get the wood this weekend.

This will be my first scratch build. I've studied the plans, and I don't see anything particularly difficult. This seems like a good plane to start with. I'm thinking it would be nice to have a build thread here for collaboration.

All I can say is that this better be good....

Status: offline 		RSteffen, Thats a great idea I will post our clubs progress with pics. We are not slated to start till Monday, March 31. We are already planning a few mods to the plane. Such as no daheadrial and 1 servo in each wing half. The latter is a great way to learn how to set up flapperons for different types of flying. Please post your progress as well.

Status: offline 		I too am planing on build the Scratch as my first airplane. 25 years ago I got close to finishing a balsa/ply sailplane but moved away to college and never came back to it. 3 months ago I purchased a simulator, which I flew 2 hours a day for two weeks before flying the Parkzone T28 that I also bought, which I can now fly fairly competently.
Anyway, I would really appreciate any tips, and photos that you folks can share as you go through the build process. I will start in a couple of weeks once I have cleared out my garage and finished installing a whole house fan in the attic!

Status: offline 		Jg, As soon as I can I will post pics. Next Monday is when we plan to start the wing. I have a bill of materials list that we made up. It should get you very close to a completed plane. We decided to built this plane in order to teach some of us new comers techniques that we can find helpful in modeling. There is more to it than just buying ARF's which is fine if you have alot of money. I plan on building 2 . 1 gas , 1 electric.

Sheet balsa
(6) 1/16x3x36" balsa
(1) 1/4x3x36" balsa
(2) 1/8x3x36" balsa
Stick balsa
(1) 1/4x 1/2x36" balsa
(2) 1/8x3/8x36" balsa
(2) 1/8x1/4x36" hard balsa
(1) 1/4x3/16x36" balsa
(1) 3/8x36 balsa triangle stock
(2) 1/4x1 1/4" aileron stock
Spruce stock
(1) 1/4x1/4x36" spruce stock
(3) 1/8x1/8x36" spruce stock
(1) 3/16x36 dowel
Plywood
1/8x4x6" liteply
(1) Sheet 1/64 ply
(3) sheets 3/32 ply
Hardware
(1) 8-32 nylon bolt
(4) Dubro 1/2a control horns
1 pack EZ hinges
Tools and glue
(1) 1/4" foam core poster board (can be found and Hobby Lobby or Office Max)
Xacto knife and # 11 blades
Good quality 3' metal yardstick
(1) bottle thin ca super glue
30 min epoxy.

Status: offline 		lrglnman, I really appreciate the bill of materials. I had a stressful day and decided to stop by the LHS tonight and got a real kick out of looking at the balsa sheets, finding the airleron control kit, looking at the monokote.

Is the poster board for creating templates??

I was also looking at the Spektrum 6i radio. Currently the only radio I have is the one that came with my Parkzone T28, so I need something new. Any input on whether this would a be good choice for a good radio system for me, for the next couple of years.

Status: offline 		Jg, no the foamcore poster board is for laying on the table . then you lay the plans over that so you can pin the wood down on the plans. you can use an old celing tile as well. just something flat that you can push t pins in . As for radios go, I would look at nothing less than a 7 channel. If you ase sure that you are going to be in this for a good while get at least a 7 channel. that way when you are ready you have the option for a lot more mixes that you can do.

Status: offline 		thanks for the feedback on the radio. It is hard to imagine using 7 channels but I definitely expect to stay with this hobby so I will go with what you say. Is 2.4ghz the way to go?

How did you go about getting the plans enlarged? I am thinking of just taking it to Kinkos and getting at least 2 copies, one to cut up to make templates. Does this make sense?

Status: offline 		I'm from a simpler school of thought in many ways. 7 channels is nice if you ever expect to fly camber altering sailplanes or similar designs where you need a separate channel for every surface rather than one per control. But if you don't expect to need that any time soon then a 4 or 5 channels is fine. But the all singing/all dancing 7 channel rigs DO come with lots of nice model memory and mixing options so that can often be worth the extra cost.

I recently got my first 2.4 set and I won't be going back. The freedom from worry about being shot down or accidentally shooting someone else down is well worth the price. It IS the way of the future. I'll continue to use my old sets for the time being but as they fail or get sold off all my new ones will be 2.4.

Kinkos or similar would be fine. If you're lucky enough to have a copier at work that handles 11x17 that's another option. Or even just with legal size. Keep in mind that you don't need to blow up the entire plan. An edge joined tiled strip with the wings and another for the fuselage will keep the seams and alignment issues to a minimum. From there just spot copy/enlarge for the specific parts and tail surfaces. There's no need at all to tile enlarge the whole plan.

Status: offline 		JG, Bruce has a good point on the radios. However if you want to do mixing, which I find extreamly useful, then 7 channels or mor is better. Alot of your planes in the ARF lines are comming out with 2 servos on the wings. I find this fantastic because I can turn the ailerons into flaps and mix a bit of elevator so my landings are super smooth I can program this to any switch on the radio I want to. each servo has its on channel.I have no experience with 2.4 but as Bruce stasted it is the future of radios. I will wear out my Futaba 7 cap first then get the 2.4 . As for the plans , here in my town their is some folks that have a CAD business which does drawings for buildings or an computer aided drawing. They inlarged my plans 250% which is to scale for $ 4.50 a copy. super cheep I think. I think Kinkos or ofice max will do it as well. Or look in your local phone book for CAD services they will be able to do it for sure.
